The Haiku alpha release has always been a bit elusive. The project has been near the alpha release for a while now, but a number of difficult data-destructive bugs kept it at bay. After an informal coding sprint, the alpha is now just a decision away.

Just to be clear though, for those who aren't familiar, the ATA bus_manager does support legacy IDE devices, it's basically just a rewrite as the IDE bus_manager code was an old hacked up version patched together in the earlier days.

It fixes several issues that prevent the IDE bus_manager from working with modern AHCI/SATA controllers (often generating interrupt handling problems and/or KDL at boot), and is a cleaner design.
